Android Nexus 4 Teamview WIFI Connection Lost Error Msg

[emjga]

Folks

I have just started to use TeamViewer
From my work PC I can connect to my Personal PC at home with no issues.

However on my Android Nexus 4 (rooted) I have teamviewer App installed (Version 9.0.1555 CL)
As soon as I start the app I get the error message "WIFI Connection Lost"
If I try and login I get the error "Failed to login check your internet connection"

I have tried to disable the WIFI connection on the phone and just use 3G
I get the error "Mobile connection lost"

However if I use other apps like Chrome browser either with WIFI or 3G then there is no issues.

Therefore it looks like there is some setting in teamview android app that does not work ?
Can anybody help and advise

Thanks
